In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
